Installation & Setup

Ethers.js v6

);

// Get the latest block
const block = await provider.getBlock('latest');
console.log('Latest block:', block.number);

// Query account balance
const balance = await provider.getBalance('0x...');
console.log('Balance:', balance.toString());

Web3.js

const Web3 = require('web3');

// Connect to Lisk mainnet
const web3 = new Web3(
  'https://api-lisk-mainnet.n.dwellir.com/YOUR_API_KEY'
);

// Get chain ID to verify connection
const chainId = await web3.eth.getChainId();
console.log('Connected to Lisk:', chainId === 1135);

// Get gas price for optimal transaction pricing
const gasPrice = await web3.eth.getGasPrice();
console.log('Current gas price:', gasPrice);

Viem

import { createPublicClient, http } from 'viem';
import { lisk } from 'viem/chains';

// Create Lisk client
const client = createPublicClient({
  chain: lisk,
  transport: http('https://api-lisk-mainnet.n.dwellir.com/YOUR_API_KEY'),
});

// Read contract data
const data = await client.readContract({
  address: '0x...',
  abi: contractAbi,
  functionName: 'balanceOf',
  args: ['0x...'],
});

Common Integration Patterns

🔄 Transaction Monitoring

Monitor pending and confirmed transactions efficiently:

// Watch for transaction confirmation
async function waitForTransaction(txHash) {
  const receipt = await provider.waitForTransaction(txHash, 1);
  
  // L2 specific: Check L1 data availability
  if (receipt.l1Fee) {
    console.log('L1 data cost:', receipt.l1Fee);
  }
  
  return receipt;
}

💰 Gas Optimization

Optimize gas costs on Lisk L2:

// Estimate L2 execution gas
const l2Gas = await provider.estimateGas(tx);

// For L1 data fees on Lisk, fees are handled automatically
// Total gas cost includes both L2 execution and L1 data posting

🔍 Event Filtering

Efficiently query contract events:

// Query events with automatic retry and pagination
async function getEvents(contract, eventName, fromBlock = 0) {
  const filter = contract.filters[eventName]();
  const events = [];
  const batchSize = 2000; // Lisk recommended batch size
  
  for (let i = fromBlock; i <= currentBlock; i += batchSize) {
    const batch = await contract.queryFilter(
      filter, 
      i, 
      Math.min(i + batchSize - 1, currentBlock)
    );
    events.push(...batch);
  }
  
  return events;
}

Performance Best Practices

1. Batch Requests

Combine multiple RPC calls for optimal performance:

const batch = [
  { method: 'eth_blockNumber', params: [] },
  { method: 'eth_gasPrice', params: [] },
  { method: 'eth_getBalance', params: [address, 'latest'] }
];

const results = await provider.send(batch);

2. Connection Pooling

Reuse provider instances to minimize connection overhead:

// Singleton pattern for provider
class BaseProvider {
  static instance = null;
  
  static getInstance() {
    if (!this.instance) {
      this.instance = new JsonRpcProvider(
        'https://api-lisk-mainnet.n.dwellir.com/YOUR_API_KEY'
      );
    }
    return this.instance;
  }
}

3. Smart Caching

Cache immutable data to reduce API calls:

const cache = new Map();

async function getCachedBlockData(blockNumber) {
  const key = `block_${blockNumber}`;
  
  if (!cache.has(key)) {
    const block = await provider.getBlock(blockNumber);
    cache.set(key, block);
  }
  
  return cache.get(key);
}

Troubleshooting Common Issues

Error: "Insufficient funds for transaction"

Lisk transactions require ETH for both L2 execution and L1 data availability:

// Always account for total gas costs
const balance = await provider.getBalance(address);
const gasEstimate = await provider.estimateGas(tx);
const gasPrice = await provider.getGasPrice();
const totalRequired = gasEstimate * gasPrice + tx.value;

if (balance < totalRequired) {
  throw new Error(`Need ${totalRequired - balance} more ETH`);
}

Error: "Transaction underpriced"

Lisk uses EIP-1559 pricing. Always use dynamic gas pricing:

// Get current fee data
const feeData = await provider.getFeeData();

const tx = {
  to: recipient,
  value: amount,
  maxFeePerGas: feeData.maxFeePerGas,
  maxPriorityFeePerGas: feeData.maxPriorityFeePerGas,
  gasLimit: 21000n
};

Error: "Rate limit exceeded"

Implement exponential backoff for resilient applications:

async function callWithRetry(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (error.code === 429 && i < maxRetries - 1) {
        await new Promise(r => setTimeout(r, 2 ** i * 1000));
      } else {
        throw error;
      }
    }
  }
}

Migration Guide

From Ethereum Mainnet

Moving from L1 to Lisk L2 requires minimal changes:

// Before (Ethereum)
const provider = new JsonRpcProvider('https://eth-rpc.example.com');

// After (Lisk)
const provider = new JsonRpcProvider(
  'https://api-lisk-mainnet.n.dwellir.com/YOUR_API_KEY'
);

// ✅ Smart contracts work identically
// ✅ Same tooling and libraries
// ⚠️ Different chain ID (1135)
// ⚠️ Separate block numbers
// ⚠️ L1 data fees apply
